FIELD OF THE INVENTION

The present invention relates generally to a collapsible bowl blank. More specifically, the present invention is a device that can be easily transformed from a flat configuration to an erected configuration.

BACKGROUND OF THE INVENTION

Containers and bowls have been manufactured in various ways over the years with improving technology creating new features for the containers and bowls. Many containers and large bowls have bulky structures and create an inconvenience for the user when looking for ways to store the object when it is not in use. One way many manufactures have attempted to avoid this problem is by creating a flat bowl or container that can then be constructed into the three-dimensional cavity. However, manually manipulating and affixing a flat blank in several areas to form a three-dimensional cavity is time consuming and complex. This results in various manufacturers simply creating permanent three-dimensional cavities, thus losing the convenience of the flat form when being stored. Other manufactures have attempted to create conical cavities to provide a cavity that is less time consuming. Unfortunately, these conical cavities can be used in various ways but require a secondary stand to ensure the cavity can stay upright.

An objective of the present invention is to provide users with a three-dimensional cavity, that can be utilized to store, food, toys, laundry, amongst various other uses. The present invention provides users with a flat device that can be easily transformed from a flat configuration to an erect three-dimensional cavity. The present invention eliminates the time-consuming erection process while ensuring a flat configuration for optimal storage capabilities. The present invention intends to provide users with a device that can be easily transformed between a flat configuration and an erect configuration as a three-dimensional cavity. In order to accomplish this, a preferred embodiment of the present invention comprises a blank edge, a first radial crease-line, a second radial crease-line, a base crease-line and a rim crease-line, configured to form a fold segment, a base section, a wall section and a rim section. Further, the base section creates an inverted conical shaped structure within the erected bowl, providing a structural base. Thus, the present invention is a blank that can be easily transformed between a flat configuration and an erect configuration where the three-dimensional cavity maybe secured, with an affixing method.

The blank includes a first radial crease-line, terminating at a center point 2801 of the blank, and a second radial crease-line, originating at the center point of the blank and defining a fold segment 2808. A base crease-line 2805 is distributed around the center point 2801. The base crease-line 2805 maybe substituted for any of the additional base crease-lines, 2806 or 2807 thereby forming larger or smaller base section sizes depending on the desired bowl size.

Other features maybe added to the invention to create functionality. The fold created by the fold segment and the under fold maybe fashioned as a spout used to direct fluids out of the main bowl structure. In other embodiments the bowl wall and base may feature holes to drain water and act as a collapsible colander. In other embodiments the internal cone within the bowl maybe used as a lemon juicer. In other embodiments there may be a cut out at the edge of the blank to serve as a spoon or thumb rest. With all the components working in tandem with each other it can be seen that, the present invention is a blank that can be easily transformed between a flat configuration and erected configuration where the three-dimensional cavity can retain its shape, with an affixing method as a precaution.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention.

It has thus been seen that the blank configured to form a collapsible bowl according to the present invention achieves the purposes highlighted earlier.
